Assessing hyolaryngeal excursion: Comparing quantitative methods to palpation at the bedside and visualization during videofluoroscopy
Dysphagia Jul 27, 2018
Brates D, et al. - Using frame-by-frame visually during videofluoroscopy (VFSS) analysis to measure anatomically scaled peak hyoid positions, researchers examined whether a binary judgment of hyolaryngeal excursion (HE) differentiates quantitative measures of hyoid movement. For this analysis, they reviewed medical records of patients who received a clinical swallowing exams (CSE) and VFSS within a 24-h period. Findings revealed that peak anterior hyoid position was significantly different between patients judged to have reduced and normal HE on palpation but no effect of clinician experience on the differentiation of objective measures based on palpation. When compared to clinician VFSS ratings, no differences were found across any objective measures. Findings suggested that clinicians should remain careful when making judgments about HE using these methods while perceptual methods might contribute to clinical decision-making.
